4.8 Service Codes
These are the most commonly used service codes for the TRAK
VMC’s
.
Service codes are broken down into the following categories: software, machine setup, diagnostics, user
options/defaults, lube pump, and I/O testing.
All Service Codes are accessed in the SET-
UP Mode by pressing the soft key for “SERV CODES”. The
service codes can be found under one of the headings listed on the main screen. Press the heading you
want to access the code in question. If you know code # you want, press the CODE # softkey and it will
take you directly to the code in question. Press CODE #, enter the number you want, then press SET.
Warning!
Certain service codes must be performed when servicing certain items on the VMC. Failure to do so can
lead to machine crashes and expensive repair work.
Do not work on the TRAK VMC unless you have been trained on these service codes.
Please see a table at the end of the service code section for the list of service codes that must be run
when certain machine components are worked on.
The Service Codes are divided into logical categories. The table below is a quick summary of the service
codes. More detailed information can be found below:
